Chapter 5 Managing Switch Stacks
Understanding Switch Stacks
Note
If the switch stack does not contain a provisioned configuration for a new switch, the switch joins the
stack with the default interface configuration. The switch stack then adds to its running configuration a
switch stack-member-number provision type global configuration command that matches the new
switch.
stack with the default interface configuration. The switch stack then adds to its running configuration a
switch stack-member-number provision type global configuration command that matches the new
switch.

Effects of Replacing a Provisioned Switch in a Switch Stack
When a provisioned switch in a switch stack fails, is removed from the stack, and is replaced with
another switch, the stack applies either the provisioned configuration or the default configuration to it.
The events that occur when the switch stack compares the provisioned configuration with the
provisioned switch are the same as those described in the

Effects of Removing a Provisioned Switch from a Switch Stack
If you remove a provisioned switch from the switch stack, the configuration associated with the removed
stack member remains in the running configuration as provisioned information. To completely remove
the configuration, use the no switch stack-member-number provision global configuration command.

Hardware Compatibility and SDM Mismatch Mode in Switch Stacks
The Catalyst 3750-E switch supports only the desktop Switch Database Management (SDM) templates.
All stack members use the SDM template configured on the stack master.
Version-mismatch (VM) mode has priority over SDM-mismatch mode. If a VM-mode condition and an
SDM-mismatch mode exist, the switch stack first attempts to resolve the VM-mode condition.

You can use the show switch privileged EXEC command to see if any stack members are in
SDM-mismatch mode.

Switch Stack Software Compatibility Recommendations
To ensure complete compatibility between stack members, use the information in this section and also
in the
in the
All stack members must run the same Cisco IOS software image and feature set to ensure compatibility
between stack members. For example, all stack members should run the cryptographic universal
software image and have the IP services feature set enabled for Cisco IOS Release 12.2(35)SE2 or later.
